Divided and this application filed November 7,

' The presentinvention' relates to means for fastening boards or pieces to supports, this application being a division of an application filed by me on. June 19, 1925, Serial No. 88,361 on benches or tables. An object of this invention is to provide a construction in which thefastening means is arranged on the rear face of the boards or. pieces. Another object of the invention is to provide a fastening means which will draw two pieces into abutment and at the same time toward the support. Still another object of the invention is to provide for holding a. narrow finishing-piece to a support in abutment with another piece also held to the support. A

still further object of theinvention is to provide a festenin g means for two abutting parts having a camming means which not only I draws the parts in firm engagement with the support but-also draws the parts into abutting relation. Another object of the invention is to make it possib le'to attach: a table or bench top made up of aplurality of strips glued together to a support in such a manner thatth'e top may'exp'and and contract transversely without producing a warped or a cracked condition in the top Toth'ese and other ends, the invention consistsof certain parts and combinations of parts all" of which will be hereinafter described": the novel features being pointed out in the appended claims.

Fig. 8' is a verticalsection through another embodiment of the invention.

In both illustrated embodiments of the in:- vention, 1 and 2 indicate two parallel angle iron pieces arranged so that a flange of each is in a plane with the other. and extend outwardly with reference to the two spaced or parallel flanges. These angle ironsmay be supported at opposite ends byupright angle irons, 3 and l, which are tied. together in any suitable manner.

In the embodiment illustrated in Figs. 1 t0 4', two boards or pieces 5 and 6, rest on the upper flanges of the support with abutting ends lying over the slot 7 between the flanges.

Arranged on the under side of each piece near the abutting ends andwithin the slot 7 is a block or casting 8 which is secured to its board or piece by screws 9 and which has '9 laterally turned. abutments 10 engaging in a groove 11 near the abutting end of each board or piece. Each block also has abevell d or cam surface 12 on its outer side, the

surfaces 12 on the two blocks converging downward'ly or away from the pieces or.

boards. On the same side the block has a wall 13 for cooperating with the wall of the slot in the support. On its inner face the block has a lateral projection 14 forming a seat or rest for the nut 15 of a fastening bolt 16. v The fastening bolt is anchored in an anchoring member 17 having, in this instance, a central opening 18 through which the bolt 16 passes. This anchoring member also has two diverging cam surfaces 19 formed by the inner faces ofv two lugs 20 which project upwardly from the upper face of the member and which have outerfa'ces 21 for-cooperating with the inner faces of the: depending flanges 'ofth'e angle. irons 1 and 2. Beyond the lugs the upper. face of the anchoring member has upwardly turned ribs 22 which cooperate with the outer faces of the downwardly extending. flanges of the angle irons 1 and 2, the. edges of such flanges abutting the upper face of the anchoring member 17 between the lugs 20 and the ribs 22. As the bolt 16 is tightened, it draws the anchoring member 17 upwardly and the boards 5 and 6 in firm engagement with the upper horizontal flanges of the angle irons. At the same time, the cam surfaces 19 of the anchoring member bear against the cam surfaces 12 on the blocks and draw the adjacent ends of the boards or pieces 5 and 6 into firm abutment. The fastening means lies within the longitudinal slot of the support, leaving the upper faces of the pieces free from any parts of the fastening devices and drawn into close abutment. The fastening device is operated entirely from the underside of the support. The anchoring member engages the flanges of the support in such a. manner as to prevent the spreading or the drawing together of the flanges under the action of the fastening means.

The embodiment shown in Figs. 5 to 7 inelusive, is the same as that shown in Figs. 1 to 4, except that the bolt 16' is arranged to be operated from the upper side of the boards or pieces 5 and 6. To this end the abutting ends of the boards or pieces 5 and 6 are provided with registering grooves or notches to form a bolt opening between the abutting ends for the passage of the bolt 16 which is anchored in the anchoring piece 17. The upper end of the bolt opening is countersunk to receive the head of the bolt which also acts to prevent lateral shifting of the abutting ends. In addition, one of the blocks 8 has a portion 23 projecting from one side thereof to fit within a pocket 24 formed in the underside of a piece 6 and the projecting portion having a screw opening 25 through which a screw 26 is passed and said projecting portion resting on the upper flange of the angle iron 2. This projection 23 carries at its outer end on its under side a hook 27 which is adapted to engage about the free edge of the horizontal flange of the angle iron and to be drawn into such connection by the camming member 17. This construction is of particular advantage when the piece 6 is in the form of a narrow finishing strip at one side of the structure unsupported at its other edge. The piece 5 is usually supported at its opposite edge as for instance, in abutting relation to another piece as shown in Fig. 1 or Fig. 5.

The embodiment illustrated by Fig. 8 is substantially the same" as that shown in Figs. 1 to 4;, except that one of the blocks 8 has aportion 23 projecting from one side thereof to fit within a pocket 24 formed in the underside of a piece 5a. This projecting portion 23, the same as a like projecting portion such as shown in Fig. 5, has a screw opening 25 through which a screw 26 is passed for securing the member 8 in place and said projecting portion 23 rests upon the upper flange of the angle iron 2. Also, as in the case of the structure of Figs. 5 to 7, this projecting portion 23 carries at its outer end on its underside a hook 27 which is adapted to engage the free edge of the longitudinal and horizontal flange of the angle iron to draw the latter into proper position in the connection by the camming member 17. The construction of this Fig. 8 particularly adapts the specific clamping arrangement of Figs. 1 to 4- for use when one of the pieces 5a is in the form of a narrow finishing strip at one side of the structure and which strip is unsupported at its outer edge.
